Sir Isaac Newton Sir Isaac Newton was an English physicist and mathematician. He was born December 25, 1642. Newton is credited with creating calculus with Gottfried Wilhelm Leibniz. Newton is recognized as one of the most influential scientists of all and an important person in the scientific revolution. Isaac Newton first described a method for approximating the real zeros of a function in text in 1671 but his work was not published until 1736. Meanwhile, a man by the name of Joseph Raphson published in writing a method of approximating the zeros of a function that were very similar to Newton’s in 1690. Now, as a compromise to both mathematicians, this method is called the Newton-Raphson method. Sir Isaac Newton also made revolutionary contributions to the world of physics including the Universal Law of Gravitation and the three laws of motion. You may have heard the story about him sitting under an apple tree and being hit on the head with an apple. It was said that when he was hit, Newton discovered gravity by asking himself why the apple had gone down and not just floated away. Through experiments, Newton found his Universal Law of Gravitation. Newton’s three laws of motion are as followed:
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
2. The relationship between an object 's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
3. For every action there is an equal and opposite reaction.
Isaac Newton was noted as building the first reflecting telescope and developed a theory of colors based on the visible spectrum shown from white light being shown through a prism. Newton was a Christian. He was never married. A French writer and philosopher
